I recently needed to recursively compare 2 directories by filename. Here's the solution:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | require 'ftools' srcDir = "/home/Music/" destDir = "/home/Music/iTunes/iTunes Music" mHash = Hash.new iHash = Hash.new #Add all files to hash Dir[srcDir + '/**/*.mp3'].each do |path| mHash[path.split('/').last] = pathend #Add all files to second hash Dir[destDir + "/**/*.mp3"].each do |path| iHash[path.split('/').last] = path end puts "Source # Files: " + mHash.length.to_sputs "Dest # Files: " + iHash.length.to_s #Compare Hashes and copy Any data Hash.each_key do |key| if iHash[key] == nil puts "Copying " + mHash[key] +" to " + destDir File.copy(mHash[key],destDir+"/") end end |
